I've been invited by a future fellow student to participate in a future
woodfiring at my future school's wood kiln. Hmmm...does that make sense?
(I haven't even REGISTERED yet! Are potters wonderful people or what?!)
Anyway, I have never had the opportunity to plan for a woodfiring before, it
was always a serendipitous matter. Now I have a little time to think things
out a bit. I have 50 lbs of Kickwheel ^10 - 11 grolleg porcelain. (sorry,
don't have the recipe). What can I do to tailor it for a wood firing to
encourage some nice flashing/woodfiring effects? I've been reading Jack
Troy's book; visions of flashing slips have been dancing in my head. I have
a very good supply of glaze/clay ingredients....unfortunately my pugmill is
still in storage. BUT...the clay itself has been frozen and thawed many
times this winter and is nice and plastic. So...any ideas and suggestions?
Thanks,

You don't need to do anything more than likely. Fine a good clear or other
liner from folks who have used that commercial body. The body will flash
itself. A little salt wash sprits on the outside of the pot would be
something for you to try----2tbl in a spray bottle but check with the kiln
owner first if this is ok.
Thank you!

An excellent flashing slip for porcelain is the famous,
Fake Avery Flashing:
Nepheline Syenite 24
Calcined EPK 30
Raw EPK 44
Neuman Clay 2 I have successfully substituted =
Redart=20
This slip should be mixed thinner than a normal slip...much thinner.. =
think nonfat milk, and either dip or spray onto bisque pots..
When the flame kisses this flashing slip it is truly beautiful.
Good Luck,
Craig

Dear Lori:
Grolleg kaolin does not have much in the way of impurities in
it (Ti, Fe, etc.) so many woodfirers use a slip of around 20-30% Neph
Sye and fill out the rest of the recipe (80-70%) with some
impurity-bearing kaolin, such as McNamee, 6-Tile, Avery, or Helmer.
the Ti and Fe in these is good for flashing, also not getting too
much flyash is good for flashing, as thicker it will go greenish.
Most woodfirers go for both effects on the same piece by judicious
stacking, hiding of surfaces, etc.
Good Luck! Hank in Eugene

Hi Lori,
I'm way behind on clayart but somehow I caught your request. One of my
students consistently uses a commercial grolleg porcelain clay in the
wood kiln. She uses a shaner shino slip ( it's been altered). I use
it alot too.
We go for flash in our wood kiln. We have found that this particular
grolleg clay body from Paoli (our local supplier) doesn't flash as well
without a little help with the slips. This slip has given us a
beautiful coral flashing with a yellow highlight that I like to call
"palomino". We flatten cone 12 in the kiln since we put in lots of
porcelain.
The recipe originally came from Dave Shaner by way of Doug Casebeer at
Anderson Ranch. The recipe is all over the place in various forms so I
will list it here. It is VERY dependable in wood.
Soda Ash 32
Spodumene 122
Custer 86
Neph Sy 360
EPK or Helmar 280
Ball Clay 120
when I use this on functional items like mugs or bowls, I use a white
liner.... Sometimes a black liner. On vases and such, I dont' use a
liner because it's always interesting to see how the interior flashes.
We had our 8th woodfiring this past weekend. I'm anxious to peek. We
have lots of this slip on porcelain in this firing. I think we have the
black gunk problem figured out but I'll talk about that later.
Happy firings!

ps. Lori it was nice to meet you at NCECA. Please keep us informed
about your exciting undertaking of grad school this fall. And, let me
know how that woodfire goes!!! good luck!
